A designed according to the principle of Ohm's Law and Through parallel resistance through a different switch,
it can produce 3 types of resistance from a new USB electronic load resistance discharge, when the entire switch
is opened, it is 2.2 ohm / 10 W, 4.7 ohm / 10 W, 2 types of resistance in parallel at the same time, In 5 V voltage
can almost produce a discharge current of 3 a.
The current size, according to ohm's law: Me = U / R Resistance in parallel
calculation formula: R = 1 / (1 / R1 + 1 / R2 + ... + 1 / Rn) K1 = 4.7Ohm / 10 W K2 = 2.2Ohm / 10 W

The loading device is working, the winding resistance caused by the large current produces very,
very high temperatures, therefore in the process of use, and only use the finish in a short period of time,
it cannot be exposed to the parts of the golden metal radiator to prevent burns! nor to the flammable contact
tester items, in order to avoid any risk of fire in the use process you must be very alert!
Load application:
It is convenient to test whether the output current of the mobile power charging treasure, mobile phone charger,
USB power supply, etc. is up to standard, as long as the USB connection is above.
And can do aging test on mobile power and USB power adapter, the resistance will be hot when aging
test discharge, the temperature is about 80~85 °C, please pay attention to anti-scalding.
Size: 6.5 x 2.2 cm / 2.56 x 0.87 inches
Note:
Allow 1-3mm error due to manual measurement. Please make sure you don't mind before bidding
Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
